What carb part is this? Reassembly help.

I need help identifying this screw from my carbs. I have them disasembled in 4 different containers, each with the parts for itself.

While slowly reassembling them here, I found a part in my carb 1 container that I cannot identify, or determine where it belongs - there is only one. Any guesses?

While I'm assembling my carbs, anything I should know besides the paper-clip bench syncing?

 

Jeezus.

Here's a Mikuni, and it's NOT a part of the carb itself. http://xjbikes.com/Forums/viewtopic/t=31061.html

It's probably a "rack" part; I'll go have a peek, I'm not recognizing it immediately.

You sure it's not a stray lawnmower part that dropped into the bin?

 

Positive. Had my carb parts in a very safe location, and very meticulously disassembled them carb by carb. It will most likely be a rack part as you've mentioned, as I broke the rack for the shaft seals.

This is the only do-hicky that I cannot locate, although I have yet to begin reassembling the rack.

 

Sorry Dude......not part of your carb rack. If it was on there, it was put on by someone other than factory. I don't see anything like that on any of my racks here.....3 xj550, 2 xj650, 2 xj900,1 xj700x racks. don't know what it is.

Yep, I just did the same thing; went and looked CLOSELY at both of my 550s and took my spare carb rack and gave it a CLOSE examination.

Dave's right; it's not a rack part.

I've had two 550 Secas for a while now, and had them QUITE a ways apart, and I don't remember anything like it.

What else do you have apart? Could it be part of your tail section luggage box, which is why I wouldn't recognize it? HAVE YOU CONFIRMED IT HAS METRIC THREADS?

I'm betting stray lawnmower part or creative substitution on the part of a PO. 'taint a (real) carb part.

 

Hmm. Thanks for the double checking, guys.

I'll reassemble without it, and see if something is missing that it fits into.
Perhaps it was used as a choke shaft screw or something odd.

I'd really like to know where it came from as there was nothing else around when I started removing parts. I'll keep you posted :?

Next time I get into the carbs on a bike, im going to do it on video so I KNOW where things go.

 

I don't even recognize it as ANY part of ANY of my xj's, either that I own, or that I've dis-assembled. I've never seen a part like that. I don't think it's from the bike at all.

You don't need to make a video.....if you don't remember where something was at, do just what you're doing now......ask here. We'll recognize it. (not just fitzy and me, of course......, but ducks and hogs ARE pretty smart...................)

Thanks for the help as usual. Which reminds me, once I finish my rebuild, you,Ducky, and Rick will be overdue for a beer.

 

Looks like a "Fabricated" --> Float Hinge Pillar Post.

Don't rule-out somebody messing with your head!!!

Back in '75,, I worked at British Leyland.
After rebuilding a MGB Gearbox; I found a Parts Envelope under a Shop Rag on my bench, that contained Tranny Thrust Washers.

Thank God there was no YouTube then.

 

Suddenly it all becomes clear! :lol:

 

When I rebuilt and dissassembled my carbs I took a thousand pictures and they saved my butt more than a few times.

 

I took a few in the process, but apparently not enough. Or as rick said, someone could be stirring the pot and goofing with my rebuild box.

 

Perhaps this is your doing...

Looks like a wonderful machine.

 

They were (that's an MGB there, sliced in half.) I had two of 'em, a '68 and a '72.

 

:::: Where is that Cut-away MG on display? ::::

Today, I looked around for something with that type of part.

The only thing remotely close was the Sliding Door Knob on a KeroSun Portable Kerosene Heater.
(It's more like a "Motion Stop or a Travel Limiter"

 

Clearly, this is the part that makes PODS work ! :lol:

 

It looks like a lawnmower part to me.

I wanna know if those are metric threads. THAT would narrow it down or elimnate it altogether.

It looks like an automotive headlight adjustment pivot or the like.

 

Do what I do.
Clean it.
Put it in the "Unique Fasteners" Drawer for eternal safekeeping
If you don't need it, ... it will remain there forever.

If you toss it out; you'll suddenly need it and learn that they don't make them any more.

 

It's a machine part & in a minute I'll remember where I've seen one, I'm thinking Nobex saw, or sim'.

 

Well now.....maybe he SHOULD toss it out. That way we can find out what it was for a lot sooner.

dave

 

the hole says it takes a pin or clip, i never took a 550 apart, it's long enough to go through a rubber grommet, how about the instrument cluster

 

Alright, alright, I'll take it to the hardware store and find out what the threads
are.

It could be gromment related, whatever it is. It's not overly clear in the pics, but there are 2 stripes of brighter silver in the center that appear to have not been exposed to the same elements.

This would definitely clue toward it being a float bowl pin (two float towers) but for the fact that I have confirmed I have four of the stock variety.

 

You shouldn't doubt Rick. He is absolutely right-every single time I have thrown something out thinking 'don't need that anymore' it turns out I DID! Last year I found an extension hose to an old vacuum cleaner I thought had long ago bit the dust. One week later I found out it was still living, working great and being used..but now only as a floor vac as I threw out the wand attachment-and no you can't go buy a new one, it was a unique style and has been discontinued. &$@!.

My Expedition needed a new harness for the instrument cluster a few months ago and guess what-Ford redesigned it and it is no longer available new or almost anywhere for that matter. After much nagging my dealer finally found one at a stealership in TN that had purchased but never installed it. It's a 2006 model truck...dangit!

I'm voting weed-eater part or chain-saw.

 

What does the non-threaded end look like, are there female threads on that end? It looks too big to be a float pivot pin.

OK, a second look shows the milled slot....I've seen these before, it's some kind of mounting post....where have I seen one of them....... :?:

 

Chain saw! Seen a part very similar to this on one of my chain saws.

 

Polock, that's not a hole....its' the end of the flathead screwdriver slot.

Others.....it's not a factory float pin. It's too short, too threaded, and too thick. It is POSSIBLE that someone MAY have lost a float pin, or broke one in a tower, or even broke a tower, and then did some cob-job of drilling larger holes, then thread one, then use this as a float pin. But I doubt it. If it turns out to be that way, meh............ But it's still not a factory original carb part that I know of.

More thoughts.......

If it's supposed to be a part a carburetor, then there should be four of them, one for each carb. If its rack-oriented, then there should be many to hold the carbs in the rack, OR there should be three of them to go between the carbs, OR there would be only 1 of them to be a stanchion for a hose, OR there would only be one of them to be the idle speed knob which is obviously not the case. Number of pieces, placement, and function also rule it out as a carb part. Again, that's all assuming someone didn't just cob something.

I'm still voting for a 2-stroker engine and it's the idle adjuster for that single simple setup. It partially blocks a tiny always open air passage that regulates an idle circuit. Just a guess of course.

 

I have solved the riddle, but let's see if you guys can with a few clues - winner gets a beer! (Or just the pride of solving the puzzle).

In the interest of solving the mystery, I took the screw to the hardware store to determine that it is an M5 with .80 pitch. It definitely has the look of some type of set screw.

After digging around the shop during some seasonal cleaning I needed anyway, I found that the screw fit into this thingy - any guesses?

 

adjustable spanner part much?

 

it's a fuel pellet from the Fukuyama power plant

 

Tach thingy

 

Can you say cresent wrench ??

Ghost

 

Gonna have to go with MiGhost on this one! Yup yup yup.....

Mccoach.....no worm drives like that inside the tachs.

Dave Fox

 

It's a wrench!
